Additional information



DPM Mechanical Recoil Reduction System for FN Herstal FNP & FNX Barrel 4.5″ & Tactical 5.3″.45ACP 

This system works due to the multi spring intricate rod (3 springs) and controls the functionality of the gun. The third spring which is contained within the rod controls the movement of the slide so it never rams on the frame.

The system includes 2 external separate springs. The springs are different in length with the longest being heaviest when the slide is on the battery, so the shooter can fine-tune the weapon for his/hers personal standards.

Overall Advantages

  • Faster follow up shots
  • Improved firing speed
  • Slide and Frame Protection
  • Elimination of jams
  • Significant recoil reduction
  • Better double-tap concentration
  • Better control and greater accuracy
